I bought a 1 gallon LL Passion Vine in the spring which bloomed profusely in the small container and in partial shade. When I repotted and moved it to a full sun position, it stopped blooming and all the leaves have small brown spots and large holes in them. It still grows robustly, but the new leaves don't stay green very long before they begin to look terrible. I water regularly and haven't seen any insects/caterpillars at all. Too much Texas sun??

let it dry out completely before watering. Mine rarely get watered by anything other than mother nature. Remember that you will eventually see the orange gulf fritterlary(sp) butterfly laying her eggs on the leaves, followed by orange spikey caterpillars that will eat the leaves. This plant is their host plant.

Thanks so much for the tips. Do you think the vine would do better in the ground rather than a pot? Or does it make any difference?

If it's in full sun, I prefer planting in the ground. The pots get too dry and hot too fast. Even though it's very drought tolerant, if let there too long without the roots being able to get to some moisture it will die.
